TOBACCO PIPE.

Specification of Letters Patent Patented Aug. 22., 1922.

Application filed September 3, 1921. Serial No. 498,297.

To all whom it may concern Be it known that 1, CHARLES LABAN, a subject of the King of Great Britain, residing at 37 Bradford Street, VValsall, in the county of Stafford, England, have invented certain new and useful Improvements in Tobacco Pipes (for which I have filed appli- Great Britain July 23, 1920, Serial #22951) and I do hereby declare the following to be a full, clear, and exact description of the same. 1

This invention relates to tobacco pipes and refers more particularly to that type of such wherein a movable tube is provided projecting into the base of the bowl, said tube having an opening or perforations on one side which are norm-ally uppermost, so that any liquid deposits from the tobacco can enter the tube, the tube being rotatable to bring the openings or perforations opposite an opening in the base of the bowl when any deposit within the tube can be removed by blowing through the stem of the pipe.

The object of the present invention is to provide a pipe of this type in which deposits are more readily removed than in those heretofore proposed, and in accordance therewith the device consists in a. tobacco pipe having a rotatable tube which projects into the base of the bowl and has an opening or openings which are normally uppermost to receive any liquid deposits from' the bowl, but which can be rotated to isolate the tube from the bowl when the deposit can be re moved, which tube is provided with an opening in its end which is normally closed or which can be normally closed, but which is or may be opened when the tube is isolated from the bowl to allow the deposit to be removed by blowing through the stem.

The means for closing the opening may be so arranged as to permit a small quantity of air normally to pass through into the movable tube, this air having a cooling effect on the smoke from the bowl.

The pipe may also be provided with additional means including a perforated diaphragm or plate disposed across the bow above the point where, the passage from the stem enters the bowl, the said plate or diaphragm preventing the formation of a plug of wet tobacco in the base of the bowl.

Referring to the drawings V Figure '1 is a sectional view of one form- I of pipe.

Figure 1 is a cross-section on an enlarged scale of the two tubes shewn in Figure 1.

Figure 2 is a similar view of another form.

Figure 2 is a perspective view showing the end of the movable tube shewn in Figure 2.

Figure 3 shews a further form.

Figures 4 and 5 are sectional elevation and plan respectively of an alternate form.

Figure 6 shews the invention applied to another form of pipe.

Figure 7 shews it applied to a further form of pipe.

Figures 8 and 9 are perspective views removed of details.

In applying my invention to a pipe with a straight stem as illustrated at Figure 1, the perforated diaphragm across the bowl for preventing the tobacco from. reaching the bottom of the bowl and falling into the movable tube where it is liable to become wet may consist of a stationary tube 1 which may be pushed into the stem 2 and may have its inner end located within the bottom of the bowl 3, the upper part of this inner end being perforated at 4.

In such a construction the movable tube 5 may also be placed through the stem. This movable tube may, for instance, be carried by the stem or by the mouth piece and a milled flange 6 or its equivalent may be provided upon the movable tube whereby it may be rotated. This milled flange or its equivalent may be located between the end of the stem and the adjacent end of the mouth piece. In this construction the movable tube consists of a length of tube extending through the stem and having its end. located within the base of the bowl, the upper side of the inner end of the tube being slotted or perforated at 7.

The stationary and the movable tubes are extended so as to project through a hole 9 in the bowl and are closed by a cap 10 which fits on to the projecting end.

-In operation with this form of the device the tobacco is par: ed and smoked in the usual way. The inner end of the stationary 1 tube prevents the tobacco from passing to the extreme bottom of the bowl or falling into the movable tube where it is liable to get wet Any liquid deposits coming either from thetobacco or-from the'mouth'piece collectv in the end of the movable tube. These deposits can the movable tube through asemi-circle and he removed by rotating with, the tube 18 being removing the closure from the end of the tubes, in which position the passage through the movable tube is isolated from the bowl and blowing through the mouth piece.

is done the contents of the movable tube are blown out through the end of the movable tube.

In the before-mentioned cap or plug on the end of the tubes, a small hole '30 is provided to register with a small hole 31 in the upper side of the portion of the fixed tube projecting through the bowl. By rotating or sliding this cap the holes may be closed or opened at will to allow .a little air to pass through the opening if required when smoking.

In the construction shewn in Figure 2, the stationary and movable tubes are arranged as before, but in this form the tubes do not extend through the bowl of the pipe. The bowl is provided-with a small hole or opening 12 whilst the end of the movable tube is partly sealed by a projection or lip 13 shaped to make contact with that side of the base of the bowl which is opposite to the stem passage, which lip normally forms a closure for the hole 12.

The opening is normally closed by the end of the movable tube. When, however, the movable tube is rotated through a semicircle this hole through the bowl is no longer sealed by the end of the movable tube because in this position it registers with the opening or perforations at the end of the movable tube.

In this arrangement by rotating or withdrawing the movable tube slightly the lip 13 may be caused to slightly uncover the hole 12 whilst the movable tube remains in communication with the bowl, so allowing a little air to paw through into the movable tube when smoking.

In Figure 3, instead of providing the movable tube with an independent flange whereby it may be turned, it is secured to the mouth piece 15 so as to be moved thereby, otherwise the arrangement it the same as Figure 1.

As shewn in Figures 4 and 5, instead of forming the stationary tube into a perforated diaphragm, the latter may, consist ofa simple plate 16 placed across the bowl of the pipe above the point where the movable tube enters the bowl. In this construction also the stationary tube may be dispensed movable and having a slotted part 19 as before, the small inner tube shewn being simply a convenient Way of connecting the tube to the mouth piece.

In applying my invention to a tobacco pipe having a bent stem as shewn in Figures 6 and 7 in Which latter construction it would be impossible to rotate the movable tube were it located in the bent stem and in the former construction it would not be con- The outer end isolateit from the bow venient to do so, I may provide the movable tube20 so that it projects into the base of the bowl either from the side of the bowl which is opposite to the stem or to enter same from some other suitable point. In this construction the fixed tube is provided with one or more apertures 21 which form the ribs 21 upon its upper side serving to prevent the tobacco from reaching the extreme base of the bowl and also to allow liquid deposits from'the tobacco to enter the movable tube. The movable tube is provided with a slot or opening 32. to permit of the passage of smoke and liquid deposits. of the movable tube in this case is disposed exterior to the bowl and is provided with a removable stopper 22 which carries with a slot 24 in the movable tube so that when the stopper is rotated'it rotates the tube. In operation the tobacco is packed and smoked in the usual Way and when it is desired to clear the bowl of liquid deposits the movable tube is rotated through a semicircle and the stopper removed. In this position the slot in the movable tube is isolated from the bowl and the deposits within the tube can be removed by blowing through the mouth piece. WVhen this has been done the stopper is replaced and the tube is turned back to its original position. With this form of the device I may also employ a stationary tube 26 having a perforated portion as shewn in Figure 6 or a perforated diaphragm 27 as shown in Figures '7 and 8 disposed across the bowl which is above the point where the passage through the stem enters the bowl. The movable tube of this construction is clearly shewn in Figure 9 and is provided with a,

longitudinal slot 29 whlch co-operates with the holes 30, 31 to admit a small quantity of air when smoking, the opening being closed as before by sliding the cap slightly.

By slightly rotating the movable tube the slot therein may be partly turned away from the opening leading from the bowl so that the volume of smoke that can be drawn through the pipe can be regulated.

What I claim then is 1. A tobacco pipe having a rotatable tube which projects into the base of the bowl and communicates axially with the exterior thereof, a part-circular tubular part adjacent the inside of thebowl, the opening of which is adapted to normally communicate with the bowl to allow any liquid deposits therefrom to pass to the tube, a closure for the end of said tube adapted to normally close it but allow it to be opened as desired, and means for rotatin the said tube so as to when the deposit can be removed by a straight blow through the stem.

a projection 23 engaging 2. A tobacco pipe having a rotatable tube reassess which projects intothe base of the bowl and communicates axially with the exterior thereof, a part-circular tubular part adjacent the inside of the bowl, the opening of which is adapted to normally communicate with the bowl to allow anyliquid deposits therefrom to pass to the tube, on the end of said tube adapted to normally form a closure for the end of said tube but allow the end to be opened on rotation of the tube, and means for rotating the said tube so as to isolate it from the bowl when the deposit can be removed by a straight blow through the stem.

3. tobacco pipe having a rotatable tube which projects into the base of the bowl and communicates axially with the exterior thereof, a part-circular tubular part adjacent the inside of the bowl, the opening of which is adapted to normally communicate with the bowl to allow any liquid deposits therefrom to pass to the tube, a stationary perforated member extending across the lower end of the bowl, and means for rotating the said tube so as to isolate it from the bowl when the deposit can be removed by a straight blow through th stem.

4. A tobacco pipe having a rotatable tube which projects into the base of the bowl and communicates axially with the exterior thereof, a part-circular tubular part adjacent the inside of the bowl, the opening of which is adapted to normally communicate with the bowl to allow any liquid deposits therefrom to pass to the tube, a stationary perforated member extending across the lower end of the bowl, a closure for the end a sector plate which projects of said tube adapted to normally close it but allow it to be opened as desired, and means for rotating the said tube so as to isolate it from the bowl when the deposit can be removed by a straight blow through the stem.

- 6. A tobacco pipe having a rotatable tube into the base of the bowl and communicates axially with the exterior thereof, a part-circular tubular part adjacent the inside of'the bowl, the opening of which is adapted to normally communicate with the bowl to allow any liquid deposits therefrom to pass to the tube,'a stationary perforated tube concentric with the said rotatable tube, a. closure for the end of said tube adapted to normally close it but allow it to be opened as desired, and means for rotating the said tube so as to isolate it from the bowl when the deposit can be removed by a straight blow through the stem.

In witness whereof I affix my signature.
